Under this model, cancer arises as the result of a single, isolated event, rather than the slow accumulation of multiple mutations. [4] The exact function of some tumor suppressor genes is not currently known (e.g. MEN1, WT1), [5] but based on these genes following the Knudson "two-hit" hypothesis, they are strongly presumed to be suppressor genes.
Prostate cancer is the second leading cause of cancer-caused fatalities in men, and within a man's lifetime, one in six men will have the disease. [104] Alterations in histone acetylation and DNA methylation occur in various genes influencing prostate cancer, and have been seen in genes involved in hormonal response. [ 105 ]
The hallmarks of cancer were originally six biological capabilities acquired during the multistep development of human tumors and have since been increased to eight capabilities and two enabling capabilities. The idea was coined by Douglas Hanahan and Robert Weinberg in their paper "The Hallmarks of Cancer" published January 2000 in Cell. [1]
New York resident Lynn Scarfuto, 72, spent several years working as a nurse navigator, helping patients through their cancer ordeals before she became a cancer
They found smaller, but still substantial, increases in other cancers in the younger generation compared to the older one: an increase of 12% for ovarian cancer and an increase of 169% for uterine ...
Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria.

After surgery, some cancer patients can safely skip radiation or chemotherapy, according to two studies exploring shorter, gentler cancer care. Researchers are looking for ways to precisely ...
Epimutations on the MLH1 gene has been found in two individuals with a phenotype of hereditary nonpolyposis colorectal cancer, and without any frank MLH1 mutation which otherwise causes the disease. The same epimutations were also found on the spermatozoa of one of the individuals, indicating the potential to be transmitted to offspring. [58]
